Abstract (en)

[origin: WO2014129953A1] The present invention proposes a system for regulation of torque demanded Tq demand from a prime mover of a vehicle, which prime mover is adapted to responding to the torque demanded Tq demand by delivering a dynamic torque Tq fw . This dynamic torque Tq fw is related by a gear ratio i to a dynamic wheel torque Tq wheel which a power train comprising the prime mover is adapted to imparting to at least one tractive wheel of the vehicle. According to the present invention the system is adapted to conducting the regulation of the torque demanded Tq demand in such a way that a difference between the torque demanded Tq demand and the dynamic torque Tq fw is actively limited by employing feedback of the dynamic torque Tq fw (t— Δt) at an earlier time t— Δt . The torque demanded Tq demand at a time t for the regulation is here limited to a maximum value Tq demand,max which exceeds the dynamic torque Tq f W (t— Δt) at an earlier time t— Δt by an offset value Tq offset max , i.e. Tq demand,max (t) = Tq fw (t -Δ t) + Tq offset>max . The torque demanded Tq demand is thus continuously varied according to the dynamic torque Tq fw , so that power train oscillations in the vehicle are reduced in number and/or magnitude.
